兩種匯率連動金融商品之研究

姜一銘, Jiang, I-Ming Unknown Date (has links)
論文摘要 Reiner(1992)說明投資人對他國投資股票時,除了關心外國股價風險外,也關切匯率變動的風險,所以他提出了匯率連動選擇權,來規避匯率風險。另外,對於規避股價風險方面,Bouaziz, Briys and Crouhy(1994;以下簡稱BBC(1994))為了防止商品受人為操縱或其他原因而產生不合理的股價風險,提出遠期生效亞洲選擇權。以及Gray及Whaley(1999)提出了重設型賣權,它不但具有一般賣權的基本特徵,也能使投資人於購買股票時,同時買進一個重設型賣權。它不但可規避股價下跌的風險,在股價上升時,因賣權的重設使得保險的底值(Floor)向上提昇而鎖住股價上漲的資本利得。 本論文分別結合上述兩種選擇權的特徵(規避匯率風險與股價風險)而設計出兩種新金融商品,分別是:「匯率連動遠期生效亞洲選擇權」與「匯率連動重設型賣權」。它們的優點為:(1)可提供投資人同時對外國股價風險及匯率風險進行避險。(2)同時,評價模型的簡單化(類似Black-Scholes模型)以及避險操作的簡易性,使發行券商(或銀行)可獲得風險控管,因此可降低避險損失,提昇利潤。

違約風險下四種新奇選擇權的評價 / Pricing four kinds of the vulnerable exotic options

林殿一, Lin, Tien-Yi Unknown Date (has links)
本論文推導違約風險下四種新奇選擇權的評價模型及其避險比率,依序為數據選擇權、寬它選擇權、互換選擇權,極值選擇權。並比較無違約風險與違約風險下的評價模型之差異。假若違約風險不存在時,違約風險下各種類型選擇權的評價模型皆會縮減成為無違約風險下所對應的評價模型。避險比率亦為如此。數值範例則印證違約風險下選擇權的價值較無違約風險選擇權的價值低。本論文完成目前尚無任何學術研究於違約風險下四種新奇選擇權的評價模型及避險比率。這是一個重要貢獻。 關鍵詞:違約風險、新奇選擇權、數據選擇權、寬它選擇權、互換選擇權、極值選擇權。 / This paper presents the analytic pricing formula and the hedging ratio of four kinds of exotic options with correlated credit risk. They are Digital options, Quanto Options, Exchange Options and Extreme-value Options, respectively. Furthermore, compare the discrepancy of the models under the condition whether the default risk exists. Finding that if there is no default risk, all models that we derive will reduce to the corresponding models with no default risks, and so do the hedging ratio. Numerical examples certify that the value of the vulnerable options will be lower than that of the ordinary options. All above that finished has not been done by existing researches and it is a chief contribution in this paper. Keywords: Exotic Options, Credit Risk, Digital Options, Quanto Options, Exchange Options, Extreme-value Options, Default Risk.
